Abstract: The present invention relates to a robot cleaner. The robot cleaner comprises: a cleaner body equipped with a driving wheel; and a cleaning nozzle mounted inside a downwardly open opening portion in a lower portion of the cleaner body so as to be able to ascend and descend. The cleaning nozzle can be supported by a plurality of ascending/descending guides and a plurality of auxiliary ascending/descending guides so that the cleaning nozzle can ascend and descend relative to the cleaner body according to changes in the height of a cleaning surface on which the cleaner body travels. Accordingly, the cleaning to nozzle rises upon being pressed by a compressible floor such as a carpet, thus solving the problem of the cleaning nozzle catching on the cleaning surface. Therefore, travel performance can be improved, and the load on a brush driving part can be reduced.
